Journey inside a cell as you follow proteins in Cell Signals. Zoom along a three-dimensional rendering of 650,000 nucleotides of human chromosome in Chromosome 11 Flyover. Processes like DNA translation, transcription, replication, and more are explained in interactive animations.

As the protein synthesis proceeds, the finished chain emerges from the ribosome. It folds up into a precise shape, determined by the exact order of amino acids. Thus the Central Dogma explains how the four letter DNA code is - quite literally - turned into flesh and blood.

A 3D animation shows how the DNA genetic "code" leads to proteins that help us develop and function. The DNA double helix contains two linear sequences of the letters A C G and T, which carry coded instructions.

Transcription is the process by which the information in DNA is copied into messenger RNA (mRNA) for protein production. Transcription begins with a bundle of factors assembling at the promoter sequence on the DNA (in red). Here, two transcription factors . …

During DNA replication, both strands of the double helix act as templates for the formation of new DNA molecules. Copying occurs at a localized region called the replication fork, which is a Y shaped structure where new DNA strands are synthesised by a multi-enzyme complex.

As DNA is transcribed into RNA it needs to be edited to remove non-coding regions, or introns, shown in green. This editing process is called splicing, which involves removing the introns, leaving only the yellow, protein-coding regions, called exons.
